   • Graphics Software Standards in Computer Graphics

     Graphics software standards help to create and set a standard for the development of computer graphics, as there are mainly two categories or general classes of computer graphics: General programming packages and Special-purpose applications packages.

     Introduction

     Each of these classes has its software standard, so understanding these standards is important to get an overview of how standards are defined in computer graphics. by understanding the classes for computer graphics it becomes easier to understand the standards for them, lets look at two of the graphics packages in computer graphics.

     Graphics Packages

     Computer graphics are divided into two package classes and each of these two packages contains one graphics software standard which is used in the computer graphics to create working software for the graphics in computers:

     General Graphics Programming Package

     A general graphics programming package helps in providing a set of functions for the graphics that are used in high-level programming languages such as C or FORTRAN etc. real-life example of a general graphics programming package can be the GL which stands for the graphics library system, it’s used in the silicon graphics.

     Some of the basic...

   • Computer Graphics Curve in Computer Graphics

     In computer graphics, we often need to draw different types of objects onto the screen. Objects are not flat all time and we need to draw curves many times to draw an object.

     Types of Curves:The curve is an infinitely large set of points. Each point has two neighbors except endpoints.

     Implicit Curves:An implicit curve or surface is the set of zeros of a function of 2 or 3 variables. We use implicit curve functions to define lines and planes. Provides no control over tangents at connection points when joining several implicit functions. Implicit functions are hard to find for many shapes. Use a function that states which points are on and off the curves. 

      All lines: Ax+By+C=0 

     In three dimensions f(X,Y, Z) defines a surface.

     A sphere centered at the origin with a radius:Curves in 3D are not so easily represented in implicit form. In general, we cannot solve for points that satisfy the implicit form.

     Cannot represent all curves (vertical lines, circles)Gives the value of one variable, the dependent variable in other terms of the other the independent variable. The most familiar form of the...

   • Computer Graphics Curve in Computer Graphics

     In computer graphics, we often need to draw different types of objects onto the screen. Objects are not flat all time and we need to draw curves many times to draw an object.

     Types of Curves:The curve is an infinitely large set of points. Each point has two neighbors except endpoints.

     • Implicit curves
     • Explicit curves
     • Parametric curves
     • Bezier curves
     • B-spline curves

     Implicit Curves:An implicit curve or surface is the set of zeros of a function of 2 or 3 variables. We use implicit curve functions to define lines and planes. Provides no control over tangents at connection points when joining several implicit functions. Implicit functions are hard to find for many shapes. Use a function that states which points are on and off the curves. 

      

     All lines: Ax+By+C=0 

     In three dimensions f(X,Y, Z) defines a surface.

     • Any plane Ax+By+ +D=0, with constants a,b,c, and d.
     • A sphere centered at the origin with a radius:

     Curves in 3D are not so easily represented in implicit form. In general, we cannot solve for points that satisfy the implicit form.

     • Implicit function form – f(x,y) = 0                                                                                                                                                                              
     • The implicit representation for the circle is:  X^2+Y^2-R^2=0 

     Gives the value of one variable, the dependent variable in other terms of the other the independent variable. The most familiar form of the curve in 2D:  

     Where y is the dependent variable, and x is...

     • Simple curve: Simple bezier curve is a straight line from the point. 
     • B0,2(u)=2Co*+u^0(1-u)*^2-0
     • B1,2(u)=2C1*U^1(1-u)*^2-1
     • B2,2(u)=2C2*U^2(1-u)*^2-2
     • Bezier curves exhibit global control points means moving control points alert the shape of the whole curve.
     • Hermit spline
     • Relaxed end spline
     • Cyclic spline
     • Anti cyclic spline
     • Normalized spline
